An Argentine prosecutor has asked a judge to declare as unconstitutional an agreement between Argentina and Iran to jointly investigate the deadly 1994 bombing of a Buenos Aires Jewish community center that local courts blamed on Tehran. Alberto Nisman, who oversaw an investigation of the AMIA center explosion that killed 85 people, presented the appeal to a federal judge on Wednesday, according to a document seen by Reuters. Nisman's appeal said the probe could result in sanctions for Argentina from international human rights bodies. Argentina's President Cristina Fernandez is allied with left-leaning leaders who have been on good terms with Tehran, such as Venezuelan President Nicolas Maduro.
